Overview

The MCU-64E Frame Controller Module provides you with direct Ethernet connectivity. You can now

control your SAS 32KD system using an internet web browser interface while maintaining compatibility with

the traditional SAS Router Control Software (RCS). The MCU-64E allows you optimum system response

times, even under the most demanding communication loads. Furthermore, the MCU-64E lets you instantly

backup and restore your frame configuration through an SD memory card (supplied).

There are two ways of communicating with your SAS 32KD System when using the MCU-64E module:

Ethernet connectivity through a 10/100 RJ45 connector or through an RS-232 serial port. Even the traditional

SAS Server Module software can communicate with blazing speed through the Ethernet port. You just need to

set the connection type to TCP/IP instead of RS-232 serial. External automation and delivery systems can also

take advantage of the direct Ethernet connectivity.

The MCU-64E can co-exist with either another MCU-64 or an MCU-32 frame controller module to

provide your 32KD system with redundant control and clock source. As we explain below, note that the ability

to have Dual MCU Operation, where each frame controller backs each other up, is an important feature of the

SAS 32KD system.

Dual MCU Operation

A significant advantage in the 32KD System is that you can use Dual MCU Frame Controllers in each

mainframe. These frame controllers keep each other up to date so you can remove or update one while the

other carries administering mainframe operations. Another advantage is the ability to have two control systems,

a Primary and a Secondary. If you use two computers and have a failure with one of them, the other will be

available to provide an interface for status and control – a ‘window’ into the system health and operation.

It is important to understand the rules applied to Dual MCU 32KD Mainframe polling operations. It is

also important to understand the rules which determine 32KD Mainframe Clock Master.

Polling Operations

The 32KD mainframe houses 21 module slots. Internal mainframe communication is orchestrated by

one of the MCU Frame Controllers. The mainframe communications is poll-response, where the Master or

Primary MCU is polling all active slots. Each participant responds immediately after being polled. The Backup

or Secondary MCU is simply listening to all communications and keeps all data in sync with the Master or

Primary MCU. The Backup MCU also responds to polls from the Master MCU, giving it a time to respond and

‘speak’ to the mainframe. Note that the Backup MCU is able to issue commands to the backplane during its

allotted time to speak. Thus, it can provide complete Control and Status to SAS Server / Router Control

Software and SAS PC Automation.

However, note that the Backup MCU is not able to provide a path for System Configuration. This means

that you cannot change Alphas, Channel Configuration, Port and Console Programming or MCU (built-in)

Automation using Router Control Software (RCS) when connected to the Backup MCU. If the Master MCU

ever stops polling or ‘goes away’, the Backup MCU will initiate polling and will become the Master controller.

At this point the Master LED on the front panel will illuminate indicating that this MCU is now the acting

Master (see Figure 1, item 4). When the other MCU is returned to service it will join the system as the Backup

MCU (i.e. not the poll-master), only resuming Master operation if it senses that the mainframe is not being

polled.

Page 5: User Guide - Sierra Automated Systems User Guide Rev E.pdf · Software and SAS PC Automation. ... (i.e. not the poll-master), only resuming Master operation if it senses that the

Sept 2015 MCU-64 User Guide, Rev E Page 5

From an operational perspective, it does not matter which MCU is operating as the Poll or Bus Master

unless you, the engineer, want to program changes to the System Configuration. In order to change system

configuration you must communicate through the acting Master MCU. Always check the Master LED indicator

on the front panel of the MCU to ensure it is the current acting Master before attempting to program changes to

the configuration or built-in automation. While the system is running you can change which MCU will operate

as Master. This is accomplished by commanding the active poll Master to Stop Polling. Please refer to the

section Stop Acting as Bus Master and Figure 7. The Master will stop polling and extinguish the front panel

Master indicator light. The Backup MCU will pick up polling duties once it senses that the poll master has

stopped and will become the Master.

Your MCU Frame Controller has a ‘dipswitch’ or ‘strap’ to set it up as either Master or Backup MCU

upon wake up (see Figure 2, item 5). Note that this preference is only valid at power up. Thus, if the mainframe

is powered up from a ‘cold start’, such as after a power failure, the MCU(s) in the mainframe will use this

information to determine who will act as the poll Master. The MCU which is strapped/switched to be a Backup

will wait 10 seconds for the Master MCU to start polling and administrating the mainframe. If the Master does

not ‘come on line’ the Backup, assuming the Master is not present or has been commanded to give up polling,

will pick up polling duties and become the Master MCU.

An interesting application to be considered is the ability to run dual SAS PC Automation: if you use

SAS PC Automation you can run the automation engine through the acting Master or primary MCU. If you

command this MCU to give up the Master polling status to another MCU it will still continue to perform the PC

Automation tasks. Thus, if this MCU is removed for service or is going to receive updated firmware you can

start the ‘backup’ PC Automation engine and it will function through the MCU to which it is connected. If the

two computers are synchronized to the same clock (e.g. network time) you can actually run both PC

Automation engines at the same time. Each Automation engine will enter the system through different MCUs.

Note that all commands will be executed twice! This isn’t a problem for a crosspoint Take command

(connection command) but may cause an issue if an opto trigger or relay are commanded to pulse twice. If you

are considering running two Automation engines simultaneously, please examine and evaluate the automation

events to ensure that ‘double’ execution will not cause unintended consequences.

Clock Master

In your SAS 32KD System there is only one clock provider at any time during operation. Note that the

MCU Polling Master status is totally independent of clock. Modules which are capable of providing clock are

MCU Frame Controllers and ANI Audio Network Interfaces. These modules have very high accuracy and

stability clock generators on board. There are two internal busses in the mainframe, A and B. Each bus is

independently driven from the clock master module. The system can optionally be fed with an AES11 master

clock source on the rear of the mainframe if you require sync to other systems in the facility. Many facilities do

not use a master clock generator, but rely on the high quality clocks of the SAS 32KD to provide master clock.

The 32KD inputs are all equipped with sample rate convertors to accept any rate of digital input.

When a mainframe is powered on, the MCU in Slot 21 is most likely to assume clock duties and provide

master clock. The ideal location for your Primary MCU (either MCU-32E or -64E) in the 32KD Mainframe is

Slot 21. This location provides for the fastest wake up and works great for master clock too. Slot 20 is a great

location for an SAS ANI-2500 Audio Network Interface module. The mainframe clock will be handed off to an

ANI module if the module is recovering clock which is distributed over the ANI Network. This is a coordinated

handoff between the module which is driving clock at power up (likely the MCU in Slot 21) and the ANI

module. When adding a second MCU module to a system, Slot 19 provides a great location for the second

MCU, leaving the ANI module in Slot 20. Slot 20 also works great for a second MCU in a single frame system.

Advanced Control

Under the Advanced Control tab (see Figure 6) you can execute the following commands. You can

hover over each button on any screen for a help tip.

Figure 6: Advanced Control Screen

Sync a New MCU to In Service MCU:

Use this command when you have first installed a Backup or Secondary MCU-64E or MCU-32 module.

See Figure 6 above, lower right corner, under MCU to MCU Sync Commands. This command allows you to

synchronize the data in the new module to the MCU Master or primary module which is in service. It is

important to sync the new module so it has a complete database and an accurate view of the status. After the

initial sync process is complete the new module will stay up to date by listening to all data communications

within the mainframe. Make sure that the Target MCU slot address is the new module! For the example above,

if the new MCU is placed in Slot 18, ensure the Target MCU is set to Slot 18. Click Send button to execute

command.

Stop Acting as Bus Master/ Switch Poll-Master to another module:

Use this command to swap frame controller Master status and operation. In Figure 7 below, we are

stopping slot 21 from acting as the Bus Master. In this example we have an MCU-32 in slot 21 and an MCU-64

in slot 18 (See Figure 13 for Frame Configuration). Select Command (020), Instruct MCU to stop acting as Bus

Master’, set the Slot Address (to Slot 21) and click the Send button: the MCU-32 in slot 21 will cease polling.

The MCU-64 in slot 18 will recognize that the polling master has stopped and it will become the Poll-Master

and start polling. This action also, by definition, means that the MCU in slot 21 will become the Secondary /

Slave MCU. As discussed previously, the Slave can still provide all status and connection control – just no

configuration programming.

Figure 7: Stop Acting as Bus Master Screen

Save Mainframe System Operational Database To SD and Restore From SD:

To Save the System Configuration data to the SD memory card, set the Slot Address to the module you

are working with, then Click on Save To SD button. Only one image is saved on an SD card. You can create

multiple cards by copying SYSCFG.txt for this MCU module to another card.
